Peter,

I would suggest

Code: [Select]

............
sn = sin(0.8 * f) * 160-x+160
cs = cos(1.2 * f) * 100-y+100
c2 = sqr(sn*sn + cs*cs)
............
to make it run ultimately fast. Oxygen doesn't have an optimizer to rearrange the code in such a way automatically. By the way, the language from which you took this snippet literally doesn't have any such optimization either.

Sure.

But something is telling me the code came all the way from there (http://forum.basicprogramming.org/index.php/topic,3408.msg24278.html#msg24278). :)

Lua doesn't have code optimization to fix these expressions so such coding style would be a speed killer for its interpretative environment. We're just not seeing this here thanks to the underlying JIT assembly. But the lag is there anyway.

Why Peter, thanks! :)

I am simply not registered at that forum and I cannot criticize Cybermonkey directly. This is why it's you who is the object of my trolling, simply because you didn't look at his careless implementation at a critical angle.

Please don't get angry with me. I am all for cleaner and faster code and not after you personally. I would have chased your friend Aurel with similar criticisms had it been his submission and not yours. :)

So, either your way or no way again?

Well, well... Happy coding! :-X
